“Nanocasting”: using SBA-15 silicas as hard templates to obtain monodispersed superparamagnetic gamma-Fe2O3 nanoparticles

Anne Davidson, Emilie Delahaye, Virginie Escax, Nissrine El Hassan, Renata Aquino, Vincent Dupuis, Regine Perzynski, Yuri Raikher

This work describes the use of mesoporous SBA-15 silicas as hard templates, for the size-controlled synthesis of oxides nanoparticles, the pores acting as nanoscale reactors. This fundamental work is mainly aimed at understanding unresolved issues concerning the occurrence and size dependence of…

Nanoparticules d’or pour les biocapteurs : lecture optique de la reconnaissance moléculaire

Souhir Boujday, Michèle Salmain

Les propriétés extraordinaires des nanoparticules d’or et/ou d’argent en ont fait des objets courtisés par les scientifiques toutes disciplines confondues. L’intensité de leur couleur ainsi que leur grande sensibilité optique au milieu environnant en font de puissants transducteurs pour les…

Direct AFM force mapping of surface nanoscale organization and protein adsorption on an aluminum substrate

Jessem Landoulsi, V. Dupres

We investigate the nanoscale organization of a superficially hydroxylated Al substrate and its effect on subsequent protein adsorption using atomic force microscopy (AFM). For this purpose we used a mode which allows a direct mapping of a variety of surface properties (adhesion, elasticity,…

Co-Al Mixed Oxides Prepared via LDH Route Using Microwaves or Ultrasound: Application for Catalytic Toluene Total Oxidation

Eric Genty, Julien Brunet, Christophe Poupin, Sandra Casale, Sylvie Capelle, Pascale Massiani, Stéphane Siffert, Renaud Cousin

Co6Al2HT hydrotalcite-like compounds were synthesized by three different methods: co-precipitation, microwaves-assisted and ultrasound-assisted methods. The mixed oxides obtained after calcination were studied by several techniques: XRD, TEM, H2-TPR and XPS. They were also tested as catalysts in…

Synthesis and Characterization of Temperature-Responsive N-Cyanomethylacrylamide-Containing Diblock Copolymer Assemblies in Water

Nicolas Audureau, Fanny Coumes, Clémence Veith, Clément Guibert, Jean-Michel Guigner, François Stoffelbach, Jutta Rieger

We have previously demonstrated that poly(N-cyanomethylacrylamide) (PCMAm) exhibits a typical upper-critical solution temperature (UCST)-type transition, as long as the molar mass of the polymer is limited, which was made possible through the use of reversible addition-fragmentation chain transfer…

Synthesis of texturally biphasic mesoporous carbon-silica composites and carbons

Cristiam F. Santa, Maguy Jaber, Jean L. Guth, Ligia Sierra

We report a new synthesis of texturally biphasic carbon-silica composites and carbons that exhibit high surface areas (up to 1500 m2 g 1), pore volumes (up to 1.9 cm3 g 1) and mesopores (4.6-6.9 nm). The composite materials have ordered mesoporous carbon domains embedded in a disordered mesoporous…

Role of active components of an Ag/Al2O3/cordierite catalyst in selective reduction of NO by ethanol

N. A. Popovich, P. I. Kiriienko, S. Solov’ev, S. Orlik, S. Dzwigaj

We show that the activity of silver/aluminum oxide catalysts in selective reduction of nitrogen oxides by ethanol increases as the Al2O3 content increases, and is determined by the optimal silver content for which Ag + cations and Ag n nanoclusters form on the Al2O3 surface. The role of silver in…

Influence of the preparation procedure on the nature and environment of vanadium in VSiBEA zeolite: XRD, DR UV-vis, NMR, EPR and TPR studies

Rafal Baran, Yannick Millot, Thomas Onfroy, Frédéric Averseng, Jean-Marc Krafft, Stanislaw Dzwigaj

Two series of VxSiBEA(I) and VxSiBEA(II) zeolites have been prepared by a two-steps postsynthesis method which consists, in the first step, in the dealumination of TEABEA zeolite by two different procedures to obtain SiBEA(I) and SiBEA(II) zeolites and then, in the second step, in contacting the…
